RETAINER FOR BALL-BEARINGS.

Specification of Letters Patent.

Patented July so, 1912.

Application filed August 26, 1911. Serial No. 646,200.

ings; to provide a retainer which will readily permit the fragments of abroken ball to fall from the bearing; to provide a retainer which issimple and durable in construction and of light weight; and to provide aretainer for ball bearings adapted to reduce the friction between theballs and the retainerto a minimunn A specific embodiment of theinvention is illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of the retainer with the balls therein. Fig.2 is a side elevation of the same. Fig. 3 is a perspective view of oneof the retainer plates.

In the construction shown, the retaining ring 1 is flattened in theplane of its radii, and is provided with a plurality of regularly spacedapertures in which the retainer plates 2 are secured. The retainerplates 2 each comprise a strip of relatively thin and strong metal whichis bent to an approxiniately U-shaped form, and has its ends reduced. insize to provide rivets 3 which extend through the apertures 1n the ring1 and are turned over to secure the plates in place. The side or legportions t of the plates lie in planes coinciding with the radii of thering and thelegs of each plate lie in close contact with the adjacentlegs of the next adjacent plates, and each two contacting legs aresecured in the same aperture in the ring. Each plate, therefore, has itstwo legs in circumferential alineinent on the ring.

The base or central portions of the plates extend clrcuinferentially ofthe ring, and each is split longitudinally and spread to provide aws 5which are adapted to engage the balls 6 with their inner margins 7,there-v by producing the least possible frictional contact between theplates and the balls.

Obviously a retainer for ball bearings cpnstructed in accordance withthis inventlon is of cheap and simple construction and its friction onthe balls will be comp arativelyslight. v

While butone specific embodiment of the invention has been herein shownand described it will be understood that many details of theconstruction shown. may be varied or omitted without departing from thescope of the claims.

I claim: .1. A retainer for. ball bearings, comprising a retaining ringhaving a plurality of apertures therethrough, and a plurality of Ushaped plates arranged with the adjacent legs of adjacent plates incontact with each other and secured in the same aperture in the ring,said plates having their central portions split circumferentially of thering and spread to provide jaws.

2. A retainer for ball bearings, comprisingva retaining ring having aplurality of apertures t-herethrough, and a plurality of U shapedretainer plates secured on said ring with .the'legs of one plate incontact with those of the next adjacent plates, the central portions ofsaid plates being slotted longitudinally of the ring and spacedtoengagethe balls with their inner margins.

In witness whereof I have hereunto subscribed myname in the presencev oftwo witnesses.
